Referrin to the drawings in detail the film magazine comprises three main pieces, that is the base 1 and the film winding casings 2 and 3. The base l has a straight flat bottom 4 adapted to fit upon the top 5 of the film moving mechanism box 6=and parallel flanges 7l and S-eXtend upwardly l from the top-5 andthe fiat bottom 4? fits between the flanges 7 and 8 A flange 9 extends upwardly 'across the front end of the boxl 6 and a-lip 10 extends from the 4forward end of the base 1 to engage under the flange 9. bracket 11 extends outwardly from therearnend. of the'v box6 and-a hand wheel screw 12 islinserted: f

upwardly through the bracket 11 and tappedfto'hold the magazine securelyinto the base 1 in place upon the box`6.

The film operating mechanism in the box 6 may be of any'su'itable construction but iS preferably the construction shown, described and claimed in my .companionl ap lication for film moving mechanism filed ay`19, 1919,\Serial No. 298,293. The film exposure parts 'of the film moving mechanism are of no consequence in this case and I have shown only the driving mechanism for operating the magazineand winding and unwinding the film. f i

a circle and extending through more than The' base 1 has a bearing facev 13 agair'istv which thecasing 2 fitsand a` secon-d bearin one-quarter of a circle.A The casings 2 and 3 'formedintegral with one side of thel annular Wall, a hub 17'at -the center ofthe web 16,

- screw threads 18 yat the opposite side of the Wall 17 from'the Web 16 and a cover 19 having external screw threads 20 fitting the.

screw threads 18 so as 'to close the chamber 21.

vA 'seat 22 .is formed in the. annular wall 15 outsid'e of the screw threads 18 and a finished face 23 is vformed outside of the seat 22. The cover 19 has a finished face 24 to fit the seat -22 and a flange 25 to fit the finished face 23 so.as` to make a tight joint to exclude dust from. the chamber 21.

Screw holes 26 and 27 are formed radially through the wall 15 and screws are inserted through the screw holes and tapped into the base 1 to hold the casing rigidly in place upon the base.

A hub '28 is' formed at the center of the cover 19, a bore 29 is formed from the inner end of the hub, a spring 30 is inserted 4into the bore 29, a bearing ballI 31 is placed in the bore against the spring and the met-al 32 is upset around the ball to `hold the ball in' place so that substantially one-quarter f of the ball projects beyond uthe inner face sleeve. The rods 34,y 35 and 36 are arranged radially and equal distances apart.

A flange 38 extends from the outer end of the bearingsleeve'37 and screws 39 are inserted through the flange 38 and tapped into` the hub 17 to hold the bearing sleeve rigidly in place.V Theopening 40 through the bearing sleeve is straight and round and a recess 41 is formed to extend outwardly from the opening 40.

Bearing rods 42, 43 and 44 are linserted ,through the flange 45 extending inwardly from the cover 19 and fixed into'the inner end of the hub' 28, said rods 42, 43 and 44 being arranged radially and fittinglclosely against the inner -face of the cover 19.

Referrlng to Figs. 15, 16 and 17, theffilni yspool 49 fits rotatably upon the sleeve 37 rand, has a notch 50'to receive the end of thel film to start the winding process. 'The spool `49 consists of .a sleeve ehambered bei tween its ends to form the bearing portions 52 fitting rotatably upon the periphery of the sleeve 37 and a head 53 fitting against the end of the sleeveand secured in place by cap fscrews 54.

A bearing sleeve coiled Wire 4belt 68 lruns around the The .head ,53 has a diametrically extend-A ing recess 55 in its inner face and a ball seat v56 in its outer face, said ball seat 56 fitting against'the. ball 31.

The belt Wheel 57 is fixed upon a spindle l58, -a bore 59 is formed in the side of-the spindle, a spring 60. is placed in the bore, a ball 61 is placed in the bore V59 against the spring, the metal 62 bein upset around the ball to hold the ball in t e bore. vThe spindle -58 vfits rotatably in the sleeve 37 and the ball 61 fits in the recess 41 to hold the spindle in place.

A tongue 63 extends from the end of the spindle 58 and fits in the recess 55, so that when the belt ^wheel 57 is; operated the film spool 49 is operated, to Wind the film.Y

When the film is Winding `or' unwinding upon the 'spool 49 the edges of the fihn may bear .more or less against the rods 34, 35 and 36 on one sideand against the rods 42, 43 and f44 upon the other side to hold the film in line upon the spool.

` Thereis a sleeve 3 7 for eaclrof the casings 2 and 3 and a'film-spool 49 foreach sleeve andpfo'r each casing. The belt Wheel 57 carryingthe spindle 58 may be moved from the casing 2 to the casing/Yr 3 or vice versa according to which Way ,the filmA is 4to be wound."y

Referring to Figs. 1 and 2, a crank shaft 64 is mountedin the box 6. A drive sprocket 65 is fixed uponl the vinner .end ofthe crank shaft 64 and a hand crank 66 is fixed upon 4the outer end of theshaft. A-belt pulley 67 is fixed upon the crankshaft 64 and a pulley 67 and around the pulley 57 so that as the hand crank 66 is operated to operate the film moving and exposure mechanism the film spool is operated to rewind the film.

The belt 68.passes through -thetop of the box 6 and is adapted to drive the belt Wheel 57 when on/either the casing 2 or the -casin 3.. Y

eferring toFigsQl, 5 and 6, an opening 69 is formed through the'top. of the box 6 and a casing 70 is inserted through the opening,`there beingan ope1'1'in'g71 through the casing.- Guide rollers '72 and 73v 'are -mounted iu the opening -71 in a .line and a third guide ,roller 74 mounted in the opening A71 in a separate line from' the line of the. rollers 72 and 73 so that the belt 68 may run upon the guide rollers 72 and 74 to drive-the Wheel .5 7 upon the casing 2 as shown. in` Fig. 1 and so that the belt may run upon .the rollers 73 and 74 to drive the Wheel 57 when operating upon the casing 3, the object being to hold the belt. 68 from running upon itself Where the belt/crosses itself. j v

The driving sprocket 65 feeds the film 7 5 to and from the filmmoving and exposure vmech'anism and the film must pass from the casing 2 to the casing 3 and from the casing ceive a cover plate 77.

i the recess \7 6.'

3 to the casing 2 through the base 1.

` eferring especially to Figs. 4, 11, 12, 13 and 14, the details of the'base 1 are as fo lows: l

The base 1 is' a casting and the faces 13 and'14 are formed upon opposite sides of-` the longitudinal center. A recess 76 is formed in one side face' of the casting to re- Before the platey 77 is applied, bores 78, 79', 80, 81 and 82 are formed in the casting from the face having Slots 83 and 84 are milled straight up and down frombetween thebores 80 and 81 and @between the bores 81 and 82 to communicate y placed in the bore ,78

89 and 90 are milled out above the bores 78 and 79.'

vwithv the bores 78 and outwardly to the casing and the film is wound taut as shown run freefl 'Slots 9 l portions 102 between 79. The portion below the bore 81 is milled out to form al chamber 85, a recess is milled in the lower faceY 4 of the casting to receive a plate 86 around the chamber 85, a guide roller 87" is placed in the bore 79,- a guide roller 88 i's andl clearance spaces Spring in the chamber 85, v each of said -bearin ings 94 and 95 exteirdin upwardly7 from the ends ofthe bar 93. t'ollers 96 and 97 are placed in the bores 80 and 82v with spindles 98 'and 99 in the half bea-rings 94, and 95.; A roller 100 is placedin the bore 81 between the roller 96 and 97, and aepin 101 is placed centrally in the'chamber' 85 below the roller 100. The film 75 is placed upon a spool in one of the casings 2 or 3 and' passed down around the pin 101 and upwardly and other spool in the other in Fig. 11, then the` plate 77 is yapplied and th'enlagazine is ready 'for use., The rollers 87, 88, 96, 97 and 100 all have'spindles 98 and-99 mounted in bearingsvto support the rollersso that the. eripheryof the rollersy 8) and 99 are formed through the annular wallseof the ca'sings 2 and 3 .to allowr the film to pass to and from the guiderollers 87 and 88.

The guide rollers 87 and 88 have reduced their ends so that thefilm will bear Iupon the-bearing portions 103 and 104, said bearing with the perforated sides of the film so as to leave the sensitized portion'of the film out of'contact with the rollers.

The rollers 96. 97 and 100-are light excluding rollers and each roller is constructcdas shown in Figs. 18 and 19. The body 105 has a longitudinally extending slit 106 and a piece of felt is placed with one end in the slit and wrapped 'around the body and the other end tucked in the slit to make a cover 107 for the roller. The rollers 96' press bearing-frames 91 and 92 are fixed f ames comprising a bar 93 and half bear- 'Fig'. 11 to the portions contacting` and 97 are pressed toward the roller 100 by the spring bearing'frames 91 and 92 so as to the film against the roller 100. The rollers are longer than the slots 83 and 8,4 and longer than the Width of the film so that fwhen the film is drawn up against the pin 101 as in Fig. 11, light is excluded fror 'the film casings 2 and 3. lOf course the lsmall portion. of film exposed in the 4chamber 85 will be spoiled by the light. i In the practicalloperating of the magazine a new unexposed film is placed in one of the casings 2 or 3 uponv the spool and threaded through'the base and attached to the other spool as shown'in Fig. 11 and if desired there maybe a plurality of the mag azines with one camera and when it is desired to use the film of a magazine, the magazine is mounted upon the camera box 6, the door 108 in the camera box opened and the operator will use a thumb and fin- Yger throughnthe opening 109 ofthe camera box to grasp the portion of the film which is extending around the pin 101 and pu/ll the loop of the film down into the camera box chamber 110 and then vpass the loop aroundl the guide rollers 111 and 112, under the soz guide rollers 113 and 114, overr the guide rollers 115 and 116 in contact with the driving sprocket 65 and pass .the loop around the film exposure mechanism 117 and close the door 108. As the camera is operated the lm will be drawn from the full spool, passed through the camera and exposed and rewound upon the empty jspool and' whfen the film -has been exposed and it is desired to'remove the magazine, the film isremovedf from the parts 112 to 117 and wound up against the pin 101,` and then the magazine is vremoved from the camera and another ,magazineA may be substituted. The exposed vfilm Amay remain in the .casing inthe zine for any reasonable length of time with-J out injury and may be developed4 at leisure. Of course the loop of the filmwhich is exposed by'opening the door 108 will be spoiled but this is a small matter.

The` opening' 109ithr0ug'h the top of the Kcamera box 6 is larger than the chamber 85 so that the film may be readily grasped and' magapulled down from the position as shown in position asjshown inFig. 4.
